Cosmetic or dermatological cleansing compositions comprising secondary alkanesulfonates

The present invention relates to cosmetic, pharmaceutical and dermatological compositions comprising secondary alkanesulfonates and betaines.

The wishes of consumers, dermatological and toxicological aspects, and the rheology of cosmetic products are closely linked to one another. Thus skin friendly products, harmless from the toxicological and ecotoxicological point of view, having favorable Theological properties are demanded.

Secondary alkanesulfonates have been known for a long time as basic surfactants, especially for detergent applications and industrial cleansers.

In US 2004/0 204 336, aqueous liquid dispersions are disclosed, comprising secondary alkanesulfonates, builders and electrolytes, stabilized by an alkylhydroxyethylammonium salt.

In US 2004/0 029 757, manual dishwashing liquid formulations are described, the surfactant mixture consisting of secondary alkanesulfonates, alkyl ether sulfates, alkyl sulfates, alkylmethyl ester sulfates, α-olefinsulfonates and a betaine.

DE 101 62 648 discloses sprayable liquid aqueous cleansers, comprising a surfactant combination of alkyl ether sulfate, secondary alkanesulfonate and amphosurfactant.

In WO 2006/050 875, hair treatment compositions are described, which contain alkyl ether sulfate or alkyl sulfate or a mixture thereof, secondary alkanesulfonate, betaine or ethercarboxylate or a mixture thereof, one or more nonionic surfactants and a cationic polymer.

In cosmetic and pharmaceutical products, secondary alkanesulfonate was employed in the past.

In contrast to alkyl ether sulfates, for example sodium lauryl ether sulfate, or alkyl sulfates, for example sodium lauryl sulfate, secondary alkanesulfonates have the disadvantage that they do not react to the customary methods of thickening, especially to the addition of common salt, with a viscosity increase, even in the presence of cosurfactants such as, for example, betaines. This applies especially in the customary ratios of basic surfactants to betaine of 7 to 3 or 8 to 2 and total surfactant contents of below 20% by weight in the formulation.

The object was to make available surfactant systems for liquid cosmetic formulations, in particular for the cleansing of the skin and hair, which are adjustable to viscosities in the range from 1000 to 30 000 mPas even at surfactant concentrations of below 20% by weight and at the same time are skin friendly and toxicologically harmless.

Surprisingly, it has been found that on combination of secondary alkanesulfonates with betaines very definitely viscous surfactant systems can be obtained if the weight ratio of secondary alkanesulfonate to betaine is chosen in the range from 6:3 to 1:2. These systems are very readily handleable, in particular at pHs of below 6, and form colorless, clear, and stable surfactant solutions, which can be used as cosmetic and pharmaceutical products in the form of shampoos, shower gels or liquid soaps.

The invention relates to stable liquid cosmetic or dermatological cleansing compositions comprising one or more secondary alkanesulfonates and one or more betaines, wherein the weight ratio of alkanesulfonate to betaine is from 6:3 to 1:2 and the viscosity of the cleansing composition is between 1000 and 30 000 mPas.

Stable cleansing compositions in the context of the present invention are formulations which show no separation, precipitation and turbidity at temperatures in the range from 0 to +50° C. and even with storage times of over several months.

The viscosities were determined by means of a Brookfield viscometer model DV-11 with spindle no. 3 at a speed of rotation of 20 1/s.

The cleansing composition according to the invention is distinguished by a good cleansing power, a good skin mildness and an esthetic appearance.

The weight ratio alkanesulfonate to betaine in the cleansing compositions according to the invention is preferably from 4:3 to 1:1.

The viscosity in the cleansing compositions according to the invention is preferably between 2000 and 10 000 mPas.

The amount of the one or more secondary alkanesulfonates and the one or more betaines in the cleansing compositions according to the invention together, based on the total weight of the compositions, is preferably between 6 and 20% by weight and particularly preferably between 8 and 15% by weight.

In a preferred embodiment of the invention, the one or more betaines is/are selected from alkylamidopropylbetaines according to formula (1)

and alkylbetaines according to formula (2)

in which R1 is an alkyl, hydroxyalkyl or alkylphenyl group, preferably an alkyl group, having 8 to 22 carbon atoms and each radical R2 is a methyl group.

In a further preferred embodiment of the invention, the one or more betaines is/are selected from the group consisting of alkylamidopropylbetaines having 8 to 18 carbon atoms in the alkyl group of the fatty acid radical, alkylbetaines having 8 to 18 carbons in the alkyl group and mixtures of these substances.

In a particularly preferred embodiment of the invention, the one or more betaines is/are selected from alkylamidopropylbetaine or a mixture of alkylamidopropylbetaine and alkylbetaine.

In a further preferred embodiment of the invention, the cleansing compositions are clear.

In the cleansing compositions according to the invention, secondary alkanesulfonates are employed whose alkyl group is saturated or unsaturated, linear or branched and which can optionally also carry hydroxyl groups, the terminal carbon atoms of the alkyl chain having no sulfonate group.

Secondary alkanesulfonates with linear alkyl groups having 8 to 20 carbon atoms are preferred, which carry one or more SO3X groups randomly distributed in the secondary position on the hydrocarbon chain. The counterion X can be a sodium, potassium, ammonium, mono-, di- or triammonium, calcium or magnesium ion or a mixture of the counterions mentioned. Sodium salts of the secondary alkanesulfonates are preferred.

In a further preferred embodiment of the invention, the one or more secondary alkanesulfonates is/are selected from C8-20 alkanesulfonates.

In a particularly preferred embodiment of the invention, the one or more secondary alkanesulfonates is/are selected from C14-17 alkanesulfonates, preferably from their sodium salts.

Alkoxylated surfactants, in particular alkyl ether sulfates, due to preparation, contain short-chain glycols in fairly small amounts, which are assessed as toxicologically harmful, so that in the market a demand for “EO-free”, i.e. ethylene oxide-free, or “ether sulfate-free” formulations exists.

The cleansing compositions according to the invention are distinguished in that they must contain no ethoxylated or propoxylated compounds. In a further preferred embodiment of the invention, the cleansing compositions therefore contain no ethoxylated or propoxylated compounds. In a particularly preferred embodiment of the invention, the cleansing compositions contain no alkyl ether sulfates.

In a further preferred embodiment of the invention, the cleansing compositions contain, in addition to the one or more secondary alkanesulfonates and the one or more betaines, one or more cosurfactants, preferably selected from the group of anionic, cationic, nonionic, zwitterionic and amphotenc surfactants.
